Storm Discussion -- updated

The main aspects of the storm have not really changed much in the past 24 hours, but we see a few items to refine in terms of the timing.

Light snow should develop Tuesday afternoon, and transition to a wintry mix during the evening hours.  A minor snow accumulation will occur, especially north and west of I-75, late in the day into the evening.

The wintry mix will transition to all rain Tuesday night through Wednesday morning.  Cold air will return around midday Wednesday and change the leftover rain back to snow for Wednesday afternoon.   Scattered snow showers will continue Wednesday night and Thursday.  A new light accumulation of snow is possible as the storm exits. 

Another factor of concern will be extremely strong winds.  Gusts may exceed 40 mph Wednesday afternoon, and could top 50 mph late Wednesday into Thursday.  This combined with the coldest air of the season for Thursday will create wind chills in the single digits.
